"Stop touching cursed symbols!"
Lumi's voice cracked like a whip, her tiny fist smacking sharply against Ryuji's hand just as his fingers brushed the jagged carving etched into the dungeon wall. The impact didn't hurt, but the reaction did—the moment his skin made contact, the symbol pulsed violently, violet veins beneath the stone flaring to life like something had just been awakened. The glow spread outward in thin, branching lines, crawling across the wall like infection.
Ryuji slowly flexed his fingers, watching the reaction with a faint, amused smirk. "…Yeah," he muttered under his breath, eyes narrowing slightly. "That's definitely not decorative."
Behind him, Kaelina's blade slid halfway free from its sheath with a low metallic whisper, her entire posture shifting in an instant. Her stance tightened, shoulders squared, feet planted—trained instinct kicking in before thought. She wasn't looking at Ryuji anymore. Her eyes were locked on the wall like it might lunge at them.
Darek stepped forward, curiosity warring with caution as he reached out. His calloused fingers brushed the stone just beside the symbol, but the moment he made contact, the purple veins twitched—subtle, but unmistakable—like something reacting to warmth. He pulled his hand back immediately, frowning. "…Yeah. Nope. Don't like that."
Elrica's staff flickered faintly in response, the mana crystals embedded along its length sputtering with unstable light. She tightened her grip, her breathing shallow as she scanned the room. "The mana here… it's not just corrupted," she said quietly, voice tight. "It feels like it's… shifting. Like it's alive."
Lumi hovered closer to the mark, her usual chaotic energy replaced by something more focused—tense, controlled. Her wings moved slower now, deliberate. "This isn't normal dungeon corruption," she said, voice lower than usual. "This is something else."
The symbol pulsed again.
Stronger.
This time, the entire wall shuddered slightly, a faint tremor running through the stone as dust trickled from the cracks above. It wasn't just the mark reacting.
The dungeon itself was responding.
Ryuji's grin didn't disappear, but his shoulders rolled once, loosening as his stance subtly shifted. "So," he said, glancing sideways at Lumi, "you gonna explain, or are we just standing here poking evil graffiti?"
She didn't answer immediately.
Which told him everything.
"…It's an Abyss mark," she said finally.
Silence settled between them, heavier than before.
Darek frowned, glancing between her and the wall. "That sounds like the kind of thing we should run from."
"It is," Lumi snapped. "But guess what? We're already inside it."
Kaelina's eyes sharpened, her voice steady but edged. "Explain. Now."
Lumi pointed at the carving, her expression tightening. "That symbol doesn't belong to this world. It's tied to something called the Abyss—something outside normal reality. It doesn't create dungeons." Her gaze shifted toward the pulsing veins spreading through the stone. "It infects them."
Elrica swallowed hard. "Infects…?"
"Corrupts the structure, the mana, the monsters—everything," Lumi said. "It twists it into something else."
Ryuji leaned casually against the wall, right beside the symbol, completely ignoring the tension building around him. "So basically," he said, tapping the stone lightly with his knuckle, "something broke reality again."
"YES!" Lumi snapped instantly. "AND YOU SHOULD BE CONCERNED!"
He tilted his head slightly, considering that. "…Are the monsters stronger?"
"…Yes."
"Better loot?"
"…Probably."
"Then I'm good."
Lumi stared at him like she might actually lose her mind. "You are unbelievable."
Kaelina exhaled slowly, forcing control back into the situation. "Enough. We proceed carefully." Her sword came fully free now, blade catching the dim light. "If this Abyss is involved, assume worst-case scenario."
Darek nodded, adjusting his grip on his greatsword. "Works for me."
Elrica stepped back slightly, raising her staff. "I'll stay behind you."
Ryuji cracked his neck, rolling his shoulders once. "Alright," he said casually.
Then he tapped the symbol again.
Lumi smacked his arm immediately. "I JUST—"
The mark flared violently.
This time there was no delay.
The veins across the wall surged outward, glowing brighter as they spread like cracks of lightning through stone. The light pulsed rapidly, syncing with something unseen, something deeper.
Then—
The temperature dropped.
Sharp. Sudden.
Cold enough that their breath misted instantly in the air.
The faint dripping echo that had filled the dungeon moments before—
Stopped.
Completely.
Silence swallowed the chamber whole.
Heavy. Suffocating.
Alive.
Kaelina's voice cut through it, low and controlled. "Everyone—ready."
Darek shifted his stance, blade angled forward.
Elrica's staff flared faintly.
Ryuji exhaled slowly, grin sharpening. "…There it is."
The shadows moved.
Not cast. Not shifting.
Moving.
Pooling along the floor like spilled ink, crawling toward the center of the chamber. They thickened, rising slowly, twisting into something unnatural—too many joints, too many angles, limbs stretching longer than they should.
The thing unfolded itself from darkness.
Its body wasn't solid. Layers of shadow overlapped and shifted, like multiple forms fighting to exist at once. Its limbs bent wrong. Its claws stretched into long, razor-thin extensions.
Then its eyes opened.
Two glowing violet slits.
Locked directly onto Ryuji.
He smirked. "Yeah," he said quietly. "Definitely my fault."
It moved.
No warning.
No sound.
One moment it existed—
The next it was gone.
Elrica gasped softly. "Where—"
"LEFT!" Lumi snapped.
Ryuji reacted instantly, grabbing Kaelina's shoulder and pulling her backward just as the creature's claws tore through the air where her throat had been. The strike was clean. Precise.
Fast enough to kill.
Kaelina twisted mid-step, blade already moving in a counter.
Steel cut through empty space.
The creature had already vanished.
Darek cursed under his breath, turning sharply. "Damn thing's fast."
The shadows along the walls rippled again.
Above them.
Behind them.
Everywhere.
Ryuji's grin widened slightly. "Good."
The creature dropped from above like a blade.
Ryuji pivoted, raising his forearm just in time.
The impact slammed into him, driving him back a step as the claws scraped against his gloves, sparks flickering where something solid met something that wasn't entirely real.
"…Sharp," he muttered.
Then he punched.
The air exploded.
The shockwave blasted outward, distorting the space in front of him as it slammed into the creature mid-attack. For a fraction of a second, its form held—flickering, resisting—before it was thrown sideways into the wall hard enough to crack stone.
Darek blinked. "…Still not used to that."
The creature twisted mid-impact, landing in a crouch.
Its form flickered.
Unstable.
Kaelina moved immediately, closing the distance in a single fluid step. Her sword flashed in a clean horizontal strike, cutting straight through the creature's torso—but the resistance felt wrong, like slicing through smoke.
"…Not solid," she muttered.
Dark strands seeped from the wound, writhing before snapping back into place.
Elrica raised her staff. "Light burst!"
A flash of white erupted outward, forcing the shadows to recoil. For a brief moment, the creature stabilized—visible, fully formed.
Ryuji saw it clearly.
Not one body.
Multiple.
Layered.
"…Got you."
He moved.
Faster.
Cleaner.
His body flowed naturally, weight shifting perfectly as his fist drove forward.
CRACK.
Bone Breaker triggered, the creature's arm snapping at an unnatural angle.
It didn't scream.
Didn't hesitate.
It attacked again.
Ryuji slipped the strike by inches and countered, driving another punch into its side. The impact forced it back this time, its form destabilizing further.
Darek roared and charged, his blade slamming into it with brute force. The hit connected this time, driving it into the wall.
Elrica followed immediately, releasing another blast of mana that cracked the stone behind it.
The creature flickered violently.
Its form tearing apart.
Then—
It vanished again.
But slower now.
Weaker.
Ryuji exhaled slowly. "…Running out of tricks."
The shadows trembled.
Then shifted behind him.
He turned instantly.
Caught it mid-materialization.
His hand shot forward, gripping its arm.
Solid.
For a moment.
"Got you."
He twisted.
SNAP.
Bone Breaker shattered the limb completely.
This time—
It screamed.
A distorted, scraping sound that made the air vibrate.
Ryuji didn't let go.
He pulled it in.
Then drove his fist forward.
BOOM.
Shockwave detonated at point-blank range.
The creature's body collapsed inward—
Then exploded outward into fragments of shadow.
The scream cut off instantly.
Silence returned.
The shadows settled.
The air stilled.
The cold lingered.
Ryuji shook his hand once, flicking off the black residue clinging to his gloves. "…Alright," he muttered. "That one actually fought back."
Darek let out a long breath. "That thing was a nightmare."
Elrica lowered her staff slowly. "…Is it gone?"
Kaelina didn't answer.
Her eyes were already on the wall.
The Abyss mark.
It pulsed again.
Brighter.
Stronger.
Cracks spread outward from it, thin fractures spidering across the stone.
Lumi floated forward slowly. "…No."
Her voice was quiet now.
Uneasy.
"That wasn't just a monster."
Ryuji glanced at her. "Yeah?"
"That was a harbinger."
"…Meaning?"
"It came from something."
The mark flared violently.
Light spilled across the chamber, jagged and unstable.
Deep within the cracks—
Something pulsed.
In rhythm.
With Ryuji's heartbeat.
Then—
He heard it.
Faint.
Distant.
But clear.
Interesting…
Ryuji's grin slowly returned.
"Well," he said, cracking his neck.
"Guess we're not done here."
Lumi didn't smile.
Because this time—
She heard it too.
